Windows Network Card sensor shows volume/speed of zero?

Hello there arjancs,
we appreciate your contact.

When adding the Windows Network Card Sensor please check whenever there are other interfaces available and if you've select the "correct one". I recommend creating a sensor for each interface and then checking which one delivers "correct" data.

Best Regards,

I've already added the Windows Network Card sensor for both available interfaces. Both sensons are showing the same problem.

Hello,
thank you for your reply.

Please download our WMI Tester, run it on the PRTG Host (or host of the Remote Probe) and scan against this particular target, please perform the "Network" test from the Advanced tab, you'll also have to provide valid credentials on the "Basic" tab. Please share the result of the test. (Please perform the test at lease twice, this will allow us to confirm whenever any counters are increasing.

Please also see our extensive WMI Troubleshooting Guide:

Edit: Improved formatting.

There are basically the results (with some formatting):

Test 1

Test 2

As you can see, reported values were exactly the same on both tests, these values are simply reported as 0(other counters like Packets Received or Packets Sent have values) and this is what PRTG reports. Unfortunately we're not able to tell you why this happens, please check with the VPS provider or with the operating system's vendor for further investigation.

Alternatively, please check our WMI troubleshooting guide:

• I have tried a lot of things to fix my WMI. What else can I try to avoid reinstalling Windows?
